I think the Swiss system is pretty good, but I don't know about the Swiss people. Are they smarter than other citizens? Are they less vulnerable to populist propaganda?
I also think this is something that works best on "smaller" scales - that is, not on the scale of France, or the UK, or Germany, but on the scale of Switzerland, Luxemburg, Austria, Belgium, Denmark, ...
Swiss culture is very small-c conservative, with heavy value on making rational, pragmatic decisions. It is no surprise that they have a system which reflects that, and performs well for that population.
